If you've bought a new charger recently, you've noticed the options are overwhelming. GaN this, wattage that, multi-port, PD 3.0, the whole thing. But the real question most people are trying to answer is simpler: do I need the expensive fast charger, or is the cheap one good enough?
We compared two of the most popular GaN chargers on Amazon right now — the INIU 100W ($32.99, 3 ports) and the UGREEN Uno 30W ($18.98, 1 port, robot-shaped). They're both USB-C, both GaN (smaller and cooler than old chargers), both from reputable brands. But they serve completely different needs.
Quick Verdict
Buy the INIU 100W if: You need to charge a laptop, or you want to charge multiple devices (phone, tablet, headphones) from one block. This replaces a power strip.
Buy the UGREEN Uno 30W if: You mostly charge a phone, want something cute on your desk, or need a compact travel charger. This is the best charger for people who already have a laptop charger.
Buy both if: You want the 100W at your desk for laptop + fast phone charging, and the 30W in your travel bag for trips. They're different tools for different situations.
⚡ INIU 100W GaN USB C Charger
$32.99 on Amazon
3 ports (2 USB-C, 1 USB-A) in a compact block that's smaller than you'd expect for 100W. It can charge a MacBook Pro at full speed while also fast-charging an iPhone and AirPods simultaneously. GaN technology keeps it cool and small. The 100W output is shared across all three ports, so plugging in more devices adjusts the power distribution automatically.
Key specs: 100W total, 3 ports, PD 3.0, GaN, compact, universal compatibility (PD 2.0/3.0).

UL-certified and built with GaN II technology.

The headline difference is 100W vs 30W, but that's not the whole story. Here's what those numbers actually mean in real life:
100W (INIU) — This is enough to charge a 13-inch MacBook Pro at full speed. It's also enough to fast-charge an iPhone 15/16 from 0 to 50% in about 30 minutes. When you have multiple devices plugged in, the charger intelligently distributes the 100W across them — so a laptop might get 65W while a phone gets 20W and AirPods get 15W.
30W (UGREEN Uno) — This is enough for a single device. It'll fast-charge any modern iPhone or Samsung Galaxy at maximum speed. It can also charge a MacBook Air, but slowly (about 2-3 hours from empty). It won't charge a 14-inch or 16-inch MacBook Pro at all while it's in use — it'll just maintain the battery level.

When to Buy the INIU 100W
You work on a laptop. This is the obvious use case. If you're plugging in a MacBook, Dell XPS, or any USB-C laptop, 100W is what you need for full-speed charging. Trying to charge a laptop with a 30W charger is like filling a bathtub with a garden hose — it'll get there eventually, but you'll be waiting a while.
You have a charging station problem. If your desk looks like a nest of cables with three different chargers plugged into a power strip, the INIU replaces all of them with one block. Phone, laptop, headphones — one plug, one cable management problem solved.
You share a charger with a partner or family. The 3-port design means you can charge two phones and a pair of earbuds simultaneously. The 100W total power is enough to fast-charge two phones at once without slowing down.
100W Power Trio: Charge Fast, Charge Three! 100W for laptops and fast-charging devices simultaneously. Compact design replaces a power strip and 3 chargers.
When to Buy the UGREEN Uno 30W
You mostly charge a phone. If 90% of your charging is an iPhone or Samsung Galaxy, 30W is the sweet spot. It's the maximum speed those phones support, so a 100W charger offers zero benefit for a phone alone. You're paying $14 extra for wattage you can't use.
You want a travel charger. The foldable plug is a game-changer for travel. It won't snag on your bag's interior, and the compact size means it fits in any pocket of a dopp kit or cable organizer. The INIU is compact for a 100W charger, but it's still bigger than the UGREEN.
You're buying a gift. The robot design with the LED status display is genuinely charming. It's the kind of thing that makes someone smile when they open it. At $18.98, it's an easy, practical gift that doesn't look like an afterthought. The INIU is a better charger, but it's not a fun gift.
You already have a laptop charger. If you're happy with your laptop's included charger, you don't need a 100W block. The 30W Uno is the perfect companion — it lives in your bag or on your nightstand for phone charging, while your laptop charger stays at your desk.
Ultra-Fast Charging: Charge your iPhone, iPad, or MacBook efficiently with GaN II technology. The intelligent LED screen shows real-time charging status. UL-certified for reliable, real-time protection.
The Price Question
The $14 difference between these two chargers is interesting. Here's how to think about it:
If you need 100W (laptop charging), the $32.99 INIU is a steal compared to what a 100W laptop charger used to cost. Apple's 96W USB-C charger sells for $79. The INIU is less than half the price, has more ports, and uses newer GaN technology.
If you only need 30W (phone charging), the $18.98 UGREEN is the smarter buy. The extra $14 for the INIU buys you nothing useful if you're just charging a phone. But keep in mind — if you ever buy a laptop in the future, you'll wish you had the 100W charger.
The Bottom Line
Our Take
This is a rare case where the right answer depends entirely on what devices you own. If you own a laptop, the INIU 100W is the obvious choice — it replaces your laptop charger and gives you extra ports for free. If you only own a phone and tablet, the UGREEN Uno 30W is all you need, and the robot design is a bonus.
If you're unsure, consider this: the INIU 100W at $32.99 is one of the best values in charging right now. It charges everything, replaces multiple chargers, and will still be useful if you upgrade your devices. The UGREEN is a better value for phone-only users, but the INIU is the better long-term investment.
